CASING FOR SHAFT-BEARINGS.

$PLEOIFICATION forming part of Letters Patent N 0. 687,404, dated.November 25, 1901.

' Application filed April 17, 1900. $erial No. 13,242. (No model.)

To all whom it may concern:

Be it known that I, AUGUST RIEBE, mechanical engineer, a subject of theKin g of Prussia, German Emperor, residing at 15 Zwingli- 5 strasse,Berlin, Kingdom of Prussia, German Empire, have invented certain new anduseful Improvements in Casings for Shaft-Bearings; and I do herebydeclare the following to be a full, clear, and exact description of thelb invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to the construction of a folding'casing forbearings, such as shaftt 5 bearings, which can always be folded in theexact centering position in relation to the center of the shaft.

The invention consists in making the bearing-casing of clamps orsegments suitably 2b hinged together and hinged to the base in orderthat when opened it may receive a suit- ]able bearing-piece, whichsurrounds the shaft in the form of a bush and Will enable this latter tobe subsequently inclosed in a cor- 2 5 rect centering position with theassistance of a screw and suitable stops. Each inserted bearing-piecemay consist of bushes, as usual, with race-rings, or of a dividedrace-ring bush, which is arranged for adjustable ball or rollerbearings.

The novel construction of the bearing-casing is illustrated in theaccompanying drawings.

Figures 1 and 2 are respectively a trans- 3 verse and a longitudinalsection of the same, while Fig. 3 is an external view of the casing in apartly-open position, Fig. etbeing an end View of the bearing in theclosed position.

The construction of the bush d, which in 0 Fig. 3 is shown only inbroken lines, is not essential for carrying out the present invention.The accurately-turned external surfaces of the piece or bush which hasto be inclosed may be made spherical, in order that 5 the bearing may bemobile, in the manner of the Sellers bearing.

a is the casing-base, the given position of which determines theposition of the axis of the shaft. The folding bearing-casing,which iscapable of being arranged on an invariable centering-line in relation tothe base a, con- 'held by its prismatic head engaging in a hollow of thebase a, runs through the slot in the shoe-shaped part of the piece q, sothat after the nuts have been loosened it can be shifted and placed outof the range of the piece g, which can then be turned outward. For thefolded or closed position of the easing it is requisite that anextension of the piece 1) should rest against a stop 7c, Figs. 1

and 3, of the base a. The bearing-surfaces for the inserted piece-bushare arranged concentrically at places in the pieces 19 q lying oppositeto one another.

.The casing constructed as above described is capable of being openedfor the purpose of cleaning the bush or adjusting it on the shaft 20,and it secures the rearrangement of the bearing in the originalcentering position. The bearing can be opened by simply loosening thescrew 0 in order to set the parts 13 q free to be turned back, Fig. 3.In this manner the inserted bearing piece or bush is accessible for thepurpose of being examined and relieved of any strain. \Vhen theadjustment. has been eifected and the bush runs properly on the shaft10, the casing 13 q is folded down for the purpose of inclosing it, thenuts of the screw cbeing screwed tightly against the shoulder s of thepiece q. The two clamps close in on the bush d and. the 0 shaft to, andthe latter is forcibly adjusted to the exact axial center, which isindicated in Fig. 3.

The bearing-casiug may be furnished with holes in suitable places, asshown at t, Fig. 5 1, in order that the lubricating material may be ableto flow readily to the interior bearing piece or bush.

What I claim isl. A casing for shaft-bearings consisting of segmentalclamps hinged together, a bearingpiece or race-ring bush, a base, ahinge-joint connecting one end of said casing with said base, and a stopor fixing-screw connecting the other end of said casing with said basewhereby said casing is fixedin its correct closed position about saidbush and may be opened out on the hinge-bolt in said base to aifordaccess to said bearing-piece, the readjustment to the exact axial centerbeing effected by the closing of the casing.

2. A casing for shaft-bearings consisting of segmental clamps p and qhinged together, a bearing-piece or race-ring bush, a base, ahinge-joint connecting clamp 19 with said base, a slotted shoe-shapedpiece on clamp q,

a fixing-screw c, and a stop 70, whereby said 15 exact axial centerbeing efiected by the clos- 2o ing of the casing.

In witness whereof I have hereunto set my hand in presence of twoWitnesses.

AUGUST RIEBE.
